A car is coasting to the right and slowing down. Neglect air resistance
Draw free body diagram.
The Attempt at a Solution
I drew the normal and the force of gravity equal and opposite of each other in the vertical direction. However, I am little confused about the direction of the force of friction. I know that the velocity vector should be pointing to the right and the acceleration vector should be pointing to the left since the car is slowing down, but what does that mean for the force of friction?
